Machine for cleaning emery-wheels



STEPHEN A. WHIPPLEAND HEMAN WHIPPLE, OF SHAFTSBURY, VERMONT.

MACHINE" FOR CLEANING EMERY-WI-IEELS.

Specification of Letters Patent No. r15,912, dated October 14, 1856.

To all whom t may concern:

Be it known that we, STEPHEN A. WHIP- rLE, of Shaftsbury, in the county of Bennington and State of Vermont, and HE- MAN WHIPPLE, of Port Richmond, in the county of Richmond and State of New York, have invented, made, and` applied to use a new and useful Improvement in Means for Cleaning Emery-Wheels, Bands, &c.; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making part of this specification, which is an isometrical perspective view of the apparatus we make use of.

In constructing emery wheels the same are covered with leather, then coated with glue, and rolled in emery sand or other polishing material. After the same have been in use some time they wear out, the emery becoming uneven in surface and the particles exposed are worn and dull, hence it becomes necessary to remove said glue or adhesive material, together with the emery or polishing material and cover the same afresh. The same remarks apply to polishing bands or belts. The usual way to remove this emery or other polishing material, is to soak the same in water, this also loosens the leather as well as destroying the balance and trueness of the wheel or hardening the band. Another plan has been to coat the wheel with moistened cloths or clay,lime,&c., also the band with similar material which involves considerable cost of labor as well as loss of emery or polishing material. i

The nature of our invention consists in bringing the surface ofthe emery wheel or band in contact with the upper surface of a revolving roller that is partially immersed water.

To enable others skilled in the art to make and use our said invention we will proceed to give a more particular description of its construction and operation reference being made t-o the accompanying drawings and the letters marked thereon, viz.

`A is a small rectangular frame open at one end for the introduction of a water box C.

B, B, are two posts, set upon and near the center of the sides of the frame A, having grooves or slots, in which adjustable boxes are confined by screws and nuts; one post B having near the top a stud z', and pulley G, confined by screw and nut for the purpose of supporting the band H, while in the operation of being cleaned. C the water box filled with water while in use. D, the cushioned roller composed of wood or,` any other material, the surface being cov ered with cloth or any other elastic substance, having the quality to transmit the water from the box to the wheel or band,

and at the same time remove the softened portion from the wheel or band, and so located that the lower part shall be partially immersed in the water of box C.. E, the pulley attached to the shaft of the roller D to give it motion. F, the polishing wheel, the surface or face of the wheel being covered with glue and emery or sand for the purpose of polishing, resting upon the top of the cushioned roller D, `and retained in its position loosely by adjustable boxes, J, one of which is seenand secured to the posts by screws and nuts. G, pulley over which the band H passes and is suspended while in the operation of being cleaned. i, the adjustable stud on which the pulley G revolves, secured to the post B by screw nut. H, the emery band, resting upon the pulley G, and passing around and between the wheel F or its substitute and the cushioned roller D. The wheel F, can easily be retained in position by a couple of arms fastened at one end of the frame by butts or hinges (as indicated by the red lines in part) with bearing placers out out on the under side of the` arms and resting angularly in position upon t-he bearings ateach end of the wheel F, thereby accommodating itself to any size wheel, without the use of the posts B, B, when used for wheels only. J, one of the adjustable boxes so formed as to retain the wheel F loosely in position on the roller D.

Operation: The several parts of the machine being constructed and arranged as herein specied the box C, filled with water, motion is given to the roller D by band or otherwise, which causes the wheel F to revolve by its own Weight, thereby receiving moisture equally upon its surface or face, until the'glue becomes suiiieiently dissolved to release the polishing material, which is carried to the Water box below by the roller D. In cleaning a band, the same results are obtained by its being suspended on the pulley G, and passing between the roller D and the Wheel F, or its substitute, thereby saving time and polishing material, and pre` serving the balance of the polishing Wheel for rapid motion, &e.

We are aware that rollers partially immersed in Water or other fluid have hereto- The use of the'roller D revolving in Contact with Water, and the superincumbent Wheel F, substantially as and for the purpose set forth.
